Management Decisions Support System for Rhodeus Amarus (Bloch, 1782) Species Populations in Oltul Mijlociu – Cibin – Hârtibaciu Natura 2000 Site (Romania)
Abstract The main threats to the Rhodeus amarus (Bloch, 1782) populations in the Natura 2000 site Oltul Mijlociu - Cibin - Hârtibaciu are the hydro technical modifications of the riverbeds, chemical pollution and poachery. ADONIS:CE is used in general for modeling business processes, but here was used in ecology/biology domain. The authors obtained a Rhodeus amarus model which included all the habitat species requirements, the indicators that provide favourable conservation status and the existing threats and pressures. The maintaining of the minor riverbed morphodynamics is very important - the meanders presence is very important for the local molluscs which are living in the inner U shape…
“Porţile de Fier/Iron Gates” Gorges Area (Danube) Fish Fauna
AbstractAn important fisheries sector of the Danube, the “Iron Gates” area, was studied by famous naturalists along the history like Marsigli, Haeckel, Kner, Antipa and Bănărescu. After more than half a century after the last main publication in this area, the “Iron Gates” Danube sector suffered significant human impact, and an assessment of the fish fauna was needed. The paper summarizes the trend of fish species along the XIX to XXIst centuries, and reveals the appearance of new species. The study includes data from about 65 fish species, belonging to: Acipenseridae, Polyodontidae, Clupeidae, Salmonidae, Esocidae, Cyprinidae, Cobitidae, Siluridae, Ictaluridae, Anguillidae, Lotidae, Gaster…
